'CooccurrenceDSM' object has no attribute 'row_col_data'

[José Manuel Martínez Martínez]

Hi, Jimmy,

thanks for the package! I've been following the tutorial and I arrived to the section on visualization. Sadly, I get an error. If I try to plot a hexbin, pcolormesh, or heatmap. Apparently the matrix was fine, I am passing a list of lists as corpus to pydsm.build:

import pydsm.visualization as visualization
visualization.heatmap(ppmi)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

---> 18     row, col, data = matrix.row_col_data
     19     histogram, xedges, yedges = np.histogram2d(col, row, bins=50, normed=True, weights=data)
     20     extent = [xedges[0], xedges[-1], yedges[0], yedges[-1]]

Do you have any clues? I've studied the code, but I am not able to find where the problem lies.

Hi @chozelinek! Apologies for the very late response. I haven't touched this project in a few years, but if it's still a problem for you I could take a look. Did you find a solution?

Closing since no response. Please let me know if it's still an issue.
